Description

The Relay Shield provides four high quality relay that can control high current loads to Arduino boards. It also provides NO (Normally Open) / NC (Normally Closed) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduino's Digital I/Os. Standardized shield form factor enables smooth connection with Arduino and compatibles. The shield also has four LED indicators to show the on/off state of each relay.

Relays are useful in switching on/off AC appliances like fan, light, motor or high current DC actuators like solenoid valve etc...

Features

Arduino Shield compatible

Relay screw terminals

Working status indicators for each relay

High quality relays

Provides NO/NC interfaces

Channel1 Interface

COM1 - Common pin

NC1 - Normally Closed. Will be connected with COM1 when RELAY1 pin is set low and disconnected when RELAY1 is high;

NO1 - Normally Open. Will be connected with COM1 when RELAY 1 pin is set high and disconnected when RELAY1 is low;

4 DIGITAL PINS TO CONTROL 4 RELAYS

RELAY1-RELAY4 pins could be connected directly with Arduino pin number of 7-4, so that four relays could be easily controlled by the Arduino
